Your program includes the following declarations union Code

Your program includes the following declarations: union Code char c; short n; float f; Code Assuming that a char requires 1 byte, a short requires 4 bytes, and a float requires 8 bytes, how much memory will the partCode variable require? 1 4 8 13 Which operator can you use to retrieve the address of a variable? & * rightarrow ! Select equivalent statements to print value of x from below options. void main () int x float y; void main () struct def my Strucrt struct def *p = &my; Struct my Struct X =25; Struct my Struct = 1.23; printf(\"%d\ \", myStruct x); printf(\"%d\ \", p rightarrow x) printf(\"%d\ \", p rightarrow x) printf(\"%d\ \", *p)

Solution

Questoin 10:

The size of the union is the size of its biggest member.

Answer is c: 8

Question 11

& is used to retrive address of variable

Answer is a:&

Question 12:

Answer is A: printf(\"%d\ \",myStruct.x);

Sample code to test:

#include <stdio.h>

struct def{
int x;
float y;
};
int main()
{
struct def myStruct;
struct def *p = &myStruct;
myStruct.x = 25;
myStruct.y = 1.23;
printf(\"%d\ \",myStruct.x);
return 0;
}

Output:

25
